| 摘 要： | 研究了放射治疗中X射线在介质中的输运过程, 编程实现了基于蒙特卡罗方法的剂量计算. 并在便于图形处理的软件Matlab中对光子输运结果进行了可视化处理. 对X射线在均匀介质和非均匀介质中的蒙特卡罗模拟结果与实测结果、其他蒙特卡罗软件模拟结果进行了比较, 结果符合较好. 实验结果表明该方法既可以获得很快的仿真速度, 又能得到精确直观的剂量计算结果, 为提高放射治疗水平具有重要的指导意义和应用价值.

| Abstract: | The photon transportation in radiotherapy is studied based on Monte Carlo method. The dose calculation based on the MC simulation package DPM has been carried out, and the results have been visualized using MEX technology of Matlab. The dose results of X-ray in homogeneity and inhomogeneity medium have been compared with experimental data and those of other MC simulation package, and these results all agree. The calculation method we proposed has the advantage of high speed and good accuracy, therefore, is applicable in practice. |
